LVIT Linear Position Sensor LR-27 Series

Alliance Sensor Group’s LR-27 series LVIT (Linear Variable Inductance Transducer) inductive position sensors are heavy duty contactless devices designed for factory automation systems and a variety of industrial and commercial applications such as solar cell positioners, wind turbine prop pitch and brakes, chute or gate positioners on off-road or agri-vehicles, and packaging machinery. The modular design, high end performance, and excellent stroke-to-length ratio make the LR-27 sensors an ideal choice for in-plant or mobile equipment OEMs.

LR-27 series sensors are currently offered in 5 full scale ranges from 50 mm to 200 mm (2 to 8 inches). Operated from a variety of DC voltages, these sensors offer a choice of four analog outputs and include ASG’s proprietary SenSet™ field recalibration feature. LR-27 products are available with either a radial exiting cable and two spherical rod eye ends or axial cable or connector terminations.

The LR series also include a smaller body version, the LR-19, for applications where a reduced body envelope is required or the LRL-27 for longer strokes lengths up to 450mm.
